void clutter_desaturate_effect_set_factor (ClutterDesaturateEffect *effect,gdouble factor);
Sets the desaturation factor for effect, with 0.0 being "do not desaturate"
and 1.0 being "fully desaturate"

gdouble clutter_desaturate_effect_get_factor
(ClutterDesaturateEffect *effect);
Retrieves the desaturation factor of effect
